REVOLVING DISPLAY DEVICE.

Specification of Letters Patent.

Patented May '7, 1918.

Application filed August 11, 1917. Serial No. 185,753.

To all whom it may concern:

Be it known that we, EDWARD L. Pm and EDWARD J. RUTHMAN, citizens of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have jointly invented certain new and useful Improvements in Revolving Display Devices, of which the following is a specification.

It is the object of our invention to provide a novel display device of simple and economical construction, comprising few parts and arranged to be readily assembled, and operating in such manner as to be rotated by currents of air applied thereto; and further, to provide the device with vanes arranged to have a suitable emblem repeated thereon so that when the vanes are rotated, the vision of one will merge into that of the other in order to observe the revolving emblems as a continuous emblem.

The invention will be further readily understood from the following description and claims, and from the drawing, in which latter:

Figure l is a front elevation of our improved device as applied to an automobile, the latter-partly broken away.

Fig. 2 is a front elevation of our improved device, with the stem and forward vane partly broken away.

Fig. 3 is a plan view of the same.

Fig. 4 is an axial section of the same, taken onthe line 44 of Fig. 3.

Fig. 5 is a cross-section. of the same taken in the plane of the line 5-5 of Fig. 4; and,

Fig. 6 is a perspective view of the parts of our improved device in separated relation.

Our improved device comprises vanes 11, of which a suitable number are employed, these vanes being preferably duplicates of one another. They are formed out of suitable material, preferably thin sheet metal, bent to form a concave side 12 and a convex side 13. The inner end of thevane is formed with a preferably reverse curl 14, the curl being preferably less than a circle in crosssection for forming a longituidinal slot 15 between the inner edge of the vane and the face of the vane toward which said edge projects.

end.

The vanes are assembled by having the curl of one vane received in the curl in a neighboring vane, which may be accomplished by hooking one curl within the other, preferably by endwise movement of said curls lengthwise of on another. Other manners of assembling, for instance the lateral hooking of one curl in the other, are within the scope of our invention.

The vanes are preferably duplicates of one another, so that when the curls of the assembled vanes are connected, the natural resilience in the metal will be sufficient to frictionally hold the vanes in assembled relation. The vanes extendsubstantially radially with relation to each other, four vanes beingshown, the outer ends of which are equidistant from each other.

A step-bearing 16 is received in one end of the assembled curls, preferably the top This step-bearing is in the form of a plug and is provided with a central bearing recess 17 the wall of which preferably tapers toward the axis of the device. The outer periphery of the bearing-plug is preferablv tapered at its recessed end, as shown at 18. for being readily received in the central bore 19 within the curls of the vanes and pushed axially therein so that the cylindrical portion of the bearing-plug is firmly frictionally held within the inner curl. The bearing-plug is preferably provided with a shoulder 20 received over the telescoped ends of the curls, and is also preferably pIO- vided with a knob 21, which adds a finished appearance to the upper part of the device. The parts thus assembled are frictionally held together and form a rigid structure.

A stem 22 is arranged to be suitably secured to any part to which it is desired to attach the device as, for instance, to the radiator of an automobile, part of which is shown at 23. The manner of securing can be accomplished in any suitablemanner, as by fixing the stem to the usual screw-cap 24 of the radiator.

The stem is provided with a tapering nd 25, preferably forming a point journal received in the recess 17 of the step-bearing. The stem is preferably of less diameter than the diameter of th central bore in the assembled curls of the vanes. A bushing 26 is received in that end of the central bore of the curls of the vanes opposite the bearingplug and is arranged to form a radial bearing for the stem. The outer periphery of its inner end is preferably tapered as shown at 27 for being readily received in said bore.

The stem is provided with a retaining part 28, arranged to be received between the bearing plug and the bushing for retaining the parts together when assembled. This retaining part is exemplified as a. spiral spring received about the stem, the spring beingpreferably forcibly slipped along. the stem to its, proper position and frictionally held in place thereon.

In assembling parts, the curls of thevanes are. received one within the other and the bearing-plug forced into: one end of the central bore of. the curls. The bushing is placed about the stem below the retaining part and the pointed end of the stem, the retaining part and the bushing in assembled relation are pushed into the. central bore of the curls of the vanes from the opposite end. of. said bore, the bushing being forced into thev central. bore and held frictionally by pressure between the curls of. the vanes and said bushing.

The parts being now assembled, and the stem being held in upright relation, the pointed end of the stem receives lodgment within the bearing-recess of the bearingplug and the bushing. forms alower radial I bearing for the vanes, this radial bearing being preferably, however, a loose hearing, so that the support of the assembled vanes'is onthe point of the stem forming bearing means offeringlittle frictional, resistance to therotation of the assembled vanes. When assembled, the retaining part is preferably slightly spaced. from the lower bushing, as shown by the space 29.

The respective sides of. the vanes may be providedwith. a suitable emblem, preferably reversely placed on the. opposite. sides of the vanes, and each of, the vanes'is preferably provided. with a similar emblem similarly placed. The/emblem shown in the drawing is a representationof the United States flag, the emblem on? the device in practice showing the flag in its usual colors.

llVhen now the device is. subjected to a current of air,- caused for instance by the movement of the automobile, when attached to. an automobile, or by: the directing of. currents. of. an. electric fan against the device, or. in other suitable manner, the. current of air is pocketed in the concave. sides of the vaneszand deflected by the convex sides of the vanes, so as to. cause. rotation of the as+ sembled vanes. with thatzside ofthe device having. the. concaveasides of thee vanes pretoward the inner ends of the vanes.

The rotation of the vanes causes a. repetition of the emblem to be brought to the view of. the observer, the emblems on succeeding vanes and on the reverse sides of the vanes appearing as continuations of oneanother for forming a continuous vision of the emblem. Y a

Having thus fully described our, invention, what we. claim: as new and desire to secure by Letters'Patent is: v
